- which i the following is a specification.

This invention relates to apparatus .for 'in'oding dough or for like purposes and has tor its'object to` provide .an improved jap- :pa'ratus'which kwill shape" ormold dough in 'ancasy land eiicientmanner`without deteriorating it.

Broadly `an Sapparatus 'for thepurpose set lforth according to my invention comprises -a'rotatable table above'which is disposed `a substantially annular former which fis `va'jda'ptc-:d to be:oscillatedfinl sucha manner that the rotation of thetabie andthemove- 'ment ofgthe l'former 'causes the dough kto travel ,along thef'jformer and mol'dsthe dough and delivers' it "from the former.

ATlfn carrying myinvention into practice, the fo'rmer comprises a substantially aniular *arcuate section chamber disposed l*slightly above 'the tableand eccentrically thereto,` the continuity'ofthe chamber bc-v 'ingiinte'r'rupted for. ra relatively short disltance-to yprovide'yone fend for feeding the dough therein andy another Aend for delivering Y:the molded ','doughtherefrom- Adjac'ent Ithis-'delivery vend suitable means is 'provided for guiding thedischarged dough "into -the `requisite [direction ora .suitable 'rece tacle.

Tie rotating table is preferably rotated 'byv .meanso'f'a frictionfdrive the speed of Awhich is-adjustable-a'nd the former is rotated eccentrically by means of a number of uniformly rotating. members of relatively short radius, -conne`cted to the former Vby arms' radiating a short distance vfrom the 'periphery of `the fformer. @wing tothe shape of--tlie'fornier and" the rotary movement of the table, the oscillating movement ofthe former gives lon and fshort sweeps .or thrusts' alternately an this'k movement" has a much better'clfect on' the' 'dough than would a succession of vvequal sweeps or thrusts. I

lnor'der that my invention may be clearly understood and .readilycarried intoieffeet, I i have 'appended' hereto two sheets, of drawings illustrating embodiment of ,Semefwhren :fs

Referringfto the drawings themachine fcom'prise's a frame li provided with internal `'webs 2the clentresfpof which .arefformed with .bosses .8v to ,carry lvloearings f or aA vertical .axially rotatable Vshaft.-/Jtfsec-ured into the {hubf 1of a circular table 6 upon the anlnularlyribbed uppersurface of which y'is 'adaptedto bepla'ced the dough'. The shaft 4 vand table 6 are rotated by means ofa friction drive comprisingha ffriction'disc 7 Vsecured to thelower end'` of theshaft and a friction wheel `8 engaging with the under surface of the disc '7. `'lhewheel 8 is carried "s'li'dablyiupon a horizontal shaft 9 supported in 'bearings 1Q in the yframe l, a pulvley ll'beingprovided yfor receiving a belt for transmitting 'rot'ar-yfmovement from a suitable lprime mover. Variations in 'the speed of rotation of the table 6 can be read- 'il-yfobtainedjby' sliding the friction wheel 8 along the shaft-9 by lmeans of a fork 12 mountedfon, a yscrew-threaded rod (not shown)` andadaptedtobe rotated, by a hand wheel 12a 3). "The bearings lO of the Idriving shaft 9 are fitted with leccentric sleeves :10F and are coupled v vtogether` by the leverarmr. le()c so that V.by depressing the v latter .the 'friction 'drive 'may "be disengaged when desired.

Supported slightly above but substantialllyjparallel to the table 61is the former 13 whichY is in the form'offan annular arcuate section channel vhavingta portion removed7 orits continuity interrupted so as to provide anlinlet ltanda discharge point 15. The discharge end of the formeris open at'th'e'top, asfat l'also that no top `pressure is app'liedfto'the dough 'as it is delivered.

vThe former ljis carriedl concentrically within a curved` frame rl'jhavingz radiating arms 17wl1'ereby itji's connected' toA a 'num berofcranks 18 'carried' by rotating vertical spindles 19 supported'in bearings 20 carried by the frame Vl. 'One of these spindles 19 is prolonged downwards and carries at its lower end a bevel pinionl meshing with a bevel pinion22 carredat .One end of a horizontal shaft "23 supported bearings Lts 24 in the frame 1, one end of this shaft having a pulley 25 for receiving rotary movement.

The former 13 is supported in eccentric relation to the table 6 and it is moved bodily in a small radius path relatively of the table which is determined by the rotation of the cranks 18. The throvv of these cranks 18 is adjustable by sliding the crank pins 18au in the crank arms 18h. Any number of different shapes and sizes of former 13 may be interchangeable in the supporting frame 16.

1n order to guide the molded dough into a desired direction, a rotating` endless band 26 is disposed across one side of the table 6 adjacent the discharge end of the former 13, so that the molded dough as it leaves the former is carried by the rotating table against the endless band, and the endless band directs the dough off the table. rlhis band 26 is guided around pulleys 27 and 28 connected by horizontal arms 29 Which pivot about the axis of the pulley 28 so that the relative positions of the discharge end of the former 13 and the band 26 can be adjusted. A pair of sprockets 30 and 31 having an endless chain 82 around them transmit rotation from the elongated spindle 19 to the spindle 33 of the pulley 28.

In operation the dough is fed by hand or any suitable feeding mechanism onto the table G so as to be carried into the inlet end of the former 18. The dough owing to its continued engagement with the rotating table and owing to the motion of the former being molded in the former and carried round to the point of delivery, Where it is taken up by the travelling band 26 and delivered on to any convenient receptacle.

In order to facilitate the molding to the desired formation of the dough, the former 3 is made of a gradually changing cross section from the inlet end to the delivery end, the inlet end being Wider but shallower than the discharge end. This Will be clear by reference to Figs. a and 5.
